In an electrolytic cell, one liter of 1M aqueous solution of MnO4− is reduced to MnO4−2 at a cathode. How many faradays would be required so that the solution becomes 0.899M MnO−4:
If hydrogen burns in air to produce oxygen, why a rocket which contains hydrogen as fuel produces smoke during its launch?
